As far as I know, the only headset/mics that need an adapter would be 
those that have a single Tip-Ring-Ring-Sleeve (TRRS) plug. The Star-Tech 
MUYHSFMM adapter looks like the right part. A search for that part on 
amazon will find it.

In the KX2 and KX3, the mic jack is TRRS, but the two rings are used for 
logic switching with an Elecraft mic (PTT, up/down). With any other mic 
(including one using this adapter), we need to go into the Menu and set 
MIC BTN to "Off" and set the radio to use VOX (or use the XMIT button).
